Analysis and checking of the shifted events

The goal of this sanity check is to see if the events predict the component even if their onsets are randomly shifted,

These analyses were done on the ~ 1 + moving.learn + moving.trial + pointing.learn + pointing.trial first order model (each participant and component modeled independently) with autocorrelation. Events were loaded, randomly shifted by a number from -30 to +30s.

Procedure

Reported values

The table below demonstrates how the shifted and non shifted betas correlate within subjects. The interactive report below then demonstrates how the same procedures applied in the main report lead to significant/non significant results when shifted events are concerned.
